Dewi Thomas Review
What an amazing product and it tastes amazing too. The strawberry one is the best! IT tastes just like a smoothie. Just make sure you shake it well as it tends to be a little lumpy
The MaxiNutrition Team:


Thank you so much for the kind words.

Our scientists have worked hard to ensure our products are the best quality & get the best results, so I will be sure to pass the message on.

Thank you for choosing MaxiNutrition.

Kind regards,



rob matthews Twice a day
I have one shake in the morning and other Late afternoon on training days. It's the first shake to enable me to train twice a day well. Would recommend to anyone who wants to push themselves to the next level.

Pauline Yates A lady's view
I see a lot of reviews from guys, but as a woman I find this shake ticks all the boxes. I struggle to eat enough food to meet the demand I place on my (over 40) body. As soon as I switched to Promax extreme combined with the extremely yummy Millionaires Shortbread protein bar in addition to my regular diet my plateau disappeared and I found it much easier to get that lean "surfer babe" look (yes ... even over40!!) One request - more yummy bars please as the others are a bit bland. (And please ... never stop doing the Strawberry as I don't like chocolate shakes 😄)
The MaxiNutrition Team:
